Characteristics.
      C F. Nichols (H. P., viii. 234) gives an account of Pop. cand., the effects of which he observed.
      "The resinous gum exuding from buds and stalks, deliciously aromatic in perfume, is widely used, to heal wounds, open sores, and eruptions, and often suppresses these latter to the harm of the patient." As an application, Nichols says, it is like Arn., dangerous, though most people are not susceptible to its poisonous effect.
      He has never seen blisters of the size of those of Pop. c. produced by any other drug: blisters hang down like bags of water the size of walnuts.
      Burning was a common symptom eyes, nose, throat, bowels, vagina.
      W. C. Stilson (H. P., xi. 88) relates a case of poisoning in a man who one evening drank rum in which Balm of Gilead buds had been placed for making a liniment.
      A few hours later his wife heard him breathing heavily, and on waking him found he could not speak.
      Stilson found him only able to speak in hoarse whispers, and he would forget in the middle of a sentence what he was going to say.
      Face ashy pale, wild look.
      Tongue and mouth dry.
      Throat dry, burning, constricted, felt as if spiders had spun webs on it.

      Since this occasion Stilson has cured several cases of catarrhal hoarseness and aphonia with Pop. c., and one case of nervous aphonia: Mrs. S. had nervous prostration, and during the attack aphonia.
      The aphonia remained after the patient got well otherwise.
